Description

Description: TECHNICAL FIELD The present invention relates to a paper folding tool for folding a large-sized drawing sheet or the like into a predetermined size.

[Conventional technology]

Architectural-related drawings, such as Japanese Industrial Standards, Column A No. 2, relatively large-format paper, should be attached to other documents, etc., the same size as that document, for example, Column B No. 5 size. Need to fold into.

To fold such drawings, anyone can do a simple fold, such as simply folding them in half, but like folding an A2 size to a B5 size,
The folding method is specified, the folding direction is both vertical and horizontal, the folding position is off the center line of the paper, and it can be folded in various directions inward and outward. Things needed skill because the folding order was complicated.

[Problems to be solved by the invention]

For this reason, folding work requires time and labor and the work efficiency is not good. Especially when folding an A2 size item to a B5 size item, it is simple to fold an A type item into a B column item. I can't fold it just by making two folds in a row,
Moreover, it was difficult to find the correct folding point because the folding method was specified.

Therefore, as a means for eliminating such inconvenience, the folding position and the folding direction as shown in, for example, JP-B-58-44129, JP-B-55-52454, JP-A-50-39309, etc. Although there are conventionally indicating plates, these only show the folding position and the folding direction, and do not show the folding order.

For this reason, it can be used by those who know the final folded state, but for those who do not know this, it is difficult to use because the order of folding, such as which line to start folding, is unknown. is there.

In this regard, Japanese Utility Model Publication No. 44-13770 discloses that a paper to be folded is placed on a folding plate and the paper is folded together with the folding body, which is confusing to the order of folding. However, there is no ingenuity to pull out the paper folded with the board from the board.

If the number of foldings is small and the folding direction is only the vertical direction, as in Japanese Utility Model Publication No. 44-13770,
It is not difficult to pull out paper, but it is not suitable for folding in both vertical and horizontal directions because it has many folding times.

An object of the present invention is to eliminate the inconvenience of the conventional example, and to easily fold a large-sized drawing sheet or the like into a small size according to a predetermined folding order in a one-touch type, which is useful for improving work efficiency. To provide.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention folds a paper sandwiched by a base plate in which a plurality of folds are defined by one fold formed in the central lateral direction and a plurality of folds formed in the vertical direction. In the paper folding tool that folds the paper on the bellows according to
The upper and lower two folding pieces located at one end of one fold formed in the central lateral direction are divided into the size of the final folding size, and the other remaining folding pieces are the above-mentioned two folding pieces. Each of the folds is divided into smaller pieces or the same size, and each fold has a slit, and two upper and lower folds are located at both ends of one fold formed in the central lateral direction. A cut is formed in the outer edge of the bent piece other than the bent piece, which is parallel to the one fold formed in the central lateral direction, and a knob is provided on the back of the one fold position formed in the central lateral direction. This is the summary.

[Action]

According to the present invention, the paper to be folded is placed on the spread base plate, the base plate is folded by sandwiching the paper according to the fold line, and from this state, the base plate and the paper are sandwiched between the base plate and the paper. If the base plate is folded according to the folds of the base plate as a unit, the paper integrated with the base plate can be simultaneously folded into a predetermined desired size.

Then, when pulling out the paper folded together with the base plate from the base plate, it is sufficient to hold the paper at the notch part formed on the base plate and pull it with the knob.At this time, the crease formed on the base plate Since there is a slit, it can be pulled out smoothly.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of a paper folding tool of the present invention, which is one example of folding an A2 size paper into a B5 size, and is made of a thick and slippery material such as paper or plastic. Using, the base plate 1 having a vertical dimension of 514 mm corresponding to twice the vertical dimension of the B5 size and a lateral dimension of 594 mm corresponding to the lateral dimension of the A2 size is obtained.

A fold line 2 that bends inward is formed in the center lateral direction of the base plate 1 with the surface of the base plate 1 facing upward, and from the left end of the base plate 1 is 182 m which corresponds to the lateral dimension of B5 size.
Vertically continuous folds 3a and 3b are formed at the position of m. The folds 3a and 3b are bent inward on the upper half 1a side of the base plate 1 and outward on the lower half 1b side.

Folds 4a, 4b that are bent inward at the center of the folds 3a, 3b and the right end of the base plate 1 in the same manner as the folds 3a, 3b at the upper half 1a side of the base plate 1 and outward at the lower half 1b side. Are continuously formed in the vertical direction.

In addition, at the midpoint between the folds 3a, 3b and the folds 4a, 4b, the folds 5a, 5b that fold inward on the upper half 1a side of the base plate 1 and inward on the lower half 1b side are made continuous in the longitudinal direction, respectively. Similarly, folds 6a and 6b similar to the folds 5a and 5b are also formed at the right end of the base plate 1 and the midpoints of the folds 4a and 4b.

Of the folds thus formed, the folds 3a, 3b, 5a, 5
Long slits 7a, 7b, 8 at both ends of b, 4a, 4b, 6a, 6b
A, 8b, 9a, 9b, 10a, 10b are provided, and slits 11 are also provided at appropriate intervals in the lateral fold line 2. The slits 11 are provided so as to reach the slits 7a, 8a, 9a and 10a formed here at the positions where they contact the folds 3a, 3b, 5a, 5b, 4a, 4b, 6a and 6b.

Furthermore, the folding pieces 13a, 13b, 14a, 14b, 15a, 15b formed by the folds 2, 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b each have a fingertip at the outer edge thereof. Size cut 18a, 18
b, 19a, 19b, 20a, 20b are formed. In addition, these preparations 1
8a to 20b are provided at the center of the outer edges of the bent pieces 13a to 15b so that they match each other when the base plate 1 is folded.

Further, on the back surface of the base plate 1, at the boundary between the bending pieces 13a and 13b and the bending pieces 15a, 15b, the tabs 22a and 22b which are bent outward at the fold lines 2 and which protrude outward are formed. It is provided at the position of the fold line 2 located.

Next, the usage will be described with reference to FIGS. 2 to 7.
To fold a B5 size paper into a B5 size paper, first lay out the base plate 1 with the front side facing upward as shown in FIG. Upper half 1a of base plate 1 by aligning the lower edge with the position of fold 2 in the center lateral direction of base plate 1 and by aligning both left and right edges with both left and right edges of base plate 1
Put it on top.

At this time, since the vertical dimension of the upper half 1a of the base plate 1 is formed to be equal to the vertical dimension of the B5 size, a vertical dimension longer than this is used.
The upper part of the A2-size paper 23 protrudes from the upper half 1a, but the protruding part 23a is left as it is.

Then, as shown in FIG. 3, the lower half 1b is bent upward from the front side through the crease 2 to form the upper half 1a and the paper.
23 and stack the paper 23 between the upper half 1a and the lower half 1
Further, as shown in FIG. 4, the protruding portion 23a of the paper 23 is folded back toward the lower front at the upper edge position of the lower half 1b and the lower half 1b.
Stack on top.

In this way, if the paper 23 is folded twice in the lateral direction in a bellows shape through the fold 2 and the edge of the lower half 1b, then, as shown in FIG.
As shown in FIG. 6, the upper half 1a, the lower half 1b, and the paper 23 sandwiched therebetween are integrally formed, the folds 3a and 3b are inward, the folds 5a and 5b are outward, and the folds 4a and 4b are inward. Also, the folds 6a and 6b are bent together along the fold lines that are provided on the outside in advance. As a result, the bent piece 13
a and 13b, 14a and 14b, 15a and 15b, and 16a and 16b are integrally folded into bellows on the folding pieces 12a and 12b, and the paper 23 sandwiched therebetween is also accompanied by this. At the same time, it is folded four times like a bellows in the vertical direction (see FIG. 7).

When the bending is completed in this way, as shown in FIG. 8, the knobs 22a and 22b are put together and pinched by the fingertips of one hand, while the bending pieces 16a and 16b are bent by the other hand.
Insert a fingertip between b and the bent pieces 12a, 12b and make a notch 18
Pinch the paper 23 at a to 20b points and place it on the upper half 1a and the lower half 1b.
Pull it upward while keeping it folded from the space. At the time of this withdrawal, since the paper 23 and the base plate 1 are integrally folded at the folds 3a and 3b, 4a and 4b, 5b and 5c, 6a and 6c, and this part, the paper 23 and the base plate 1 are Although it is in a close contact state, since slits 7a, 7b, 8a, 8b, 9a, 9b, 10a, 10b, 11 are formed in this place, the place where the paper 23 contacts the base plate 1 is reduced, and
Paper 23 folded at the folding pieces 16a, 16b, 12a, 12b
Since it does not pinch, pulling resistance is reduced and pulling out is performed smoothly.

In this way, as shown in Fig. 9, A2 size paper is placed horizontally 2
The paper 23, which has been folded into a bellows shape four times in the vertical direction and four times in the vertical direction, and has a size of B5 size, is pulled out from the base plate 1.

Then, in order to attach this B5 size folded paper to another B5 size document or the like, for example, by folding the left corner of the protruding portion 23a toward the upper edge by 45 degrees, the binding margin can be obtained.

In addition, in the above-mentioned embodiment, the A2 size paper is described as being folded into the B5 size, but by appropriately determining the size and the fold points and the direction of the base plate, the paper of various sizes can be obtained. Can be folded into various sizes.

〔The invention's effect〕

As described above, the paper folding tool of the present invention can be formed by, for example, stacking a sheet of paper on it and folding it according to the fold line according to the folding method according to a predetermined location and order.
It can be folded into a small size of B5 size with a single touch, and even when the base plate and paper are folded together, the paper can be easily pulled out from the base plate, so the labor and time required for folding work can be saved, and work can be done. The efficiency can be improved.
